I have a confession to make. I was wrong. You see, I once thought that teaching was lecturing, and I thought that because that is how my graduate mentors taught me to teach.
But I was wrong. Studies have shown that lecturing has little to do with teaching. A University of Maryland study found that right after a physics lecture, almost none of the students could answer the question: “What was the lecture you just heard about?” Another physics professor simply asked students about the material that he had presented only 15 minutes earlier, and he found that only ten percent showed any sign of remembering it (Freedman, 2012).
